Abstract (en)

A tool calibrator and method including a gauge head with a surface for chucking in a workpiece holder on a machine lathe. A plurality of contact surfaces on the gauge head function to contact the tool cutting edge when moved transverse to and parallel to the rotational axis of the workpiece holder. Electrical sensing circuitry detect resulting contacts and relay the same to the numerical control circuitry of the lathe for automatically determining relative position of the tool cutting edge. This input data is used to control movement of the tool in its tool holder after the gauge head has been removed and a workpiece mounted for the machining operation.
